Rescue crews are on standby as floodwaters from Nepal move toward Bihar.

Following severe flash floods in the Himalayan nation, Bihar, which borders Nepal, has been placed on alert. The administration has warned that water levels in the River Gandak may rise significantly during the next five to six hours.

Strong floodwaters in Nepal were seen in horrifying images smashing into structures and carrying away homes and cars. Over 20 people died in the catastrophe, which occurred close to the Tibetan border. More than 130 Indian visitors are among the missing.

Uttar Pradesh and Bihar are on high alert due to the catastrophic flash flood in neighboring Nepal. Many rivers, including the Gandak and the Kosi, flow into Bihar from Nepal. Before they reach India, these rivers come from Tibet. The next five to six hours are critical, according to Bihar Deputy Chief Minister Vijay Chaudhary, who has called on residents of neighboring districts to exercise caution. But there was no need to panic, he continued. “The problem is bigger than before, but the situation is under control presently,” Chaudhary stated.
Rising floods from Nepal are predicted to cause a surge in the Gandak River, according to Chaudhary, the state minister of water resources.

In the next two to three hours, the water is probably going to flow to the Valmikinagar barrage. The Bhote Koshi River surged, causing the flash flood in Nepal. The river travels through central Nepal after joining the Trishuli River, which has its source in Tibet. It is anticipated that the floodwater will go via the Trishuli River to Devghat, a well-known pilgrimage destination in Nepal, before entering the Gandak River and finally arriving in Bihar.

According to the minister, the Gandak’s present low water level is a “positive factor”. According to the preliminary analysis, the Valmikinagar barrage may potentially handle up to 2.5 lakh cusecs of water. All 36 of the Gandak barrage’s gates have been opened to allow water to flow freely as a precaution. The barrage now discharges about 86,000 cusecs.

At the Devghat location in Nepal, the water level of the Narayani River (known as Gandak in India) was measured at 4.77 meters. Nine meters is the danger mark. It will probably take three to four hours for the water to reach the Gandak barrage if the level at Devghat rises.
